04 · Handling and storage
Storing and handling 1,3,5-triazine-2,4,6-triamine
Storage conditions
Store in tightly closed containers in a cool, well vented area away form strong oxidizers and strong acids. Where possible, automatically pump liquid from drums or other storage containers to process containers. A regulated, marked area should be established where this chemical is handled, used, or stored in compliance with OSHA standard 1910.1045.

Incompatible materials
Strong oxidizers, strong acids.
Source: Hazardous Substances Data Bank (HSDB)
Reactivity
MELAMINE is incompatible with strong oxidizing agents and strong acids (NTP, 1992). Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Safety Data Sheet
Getting an SDS for 1,3,5-triazine-2,4,6-triam…
A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of 1,3,5-triazine-2,4,6-t… issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.
